Sha256Crypto

Platform-specific SHA-256 cryptographic hash function.

Production-Ready Implementations

All implementations use audited, battle-tested cryptographic libraries:

JVM

• Library: Java Security API (java.security.MessageDigest)

• Algorithm: SHA-256

• Security: FIPS 140-2 compliant, industry standard

iOS/macOS (Native)

• Library: libsodium (via C interop)

• Algorithm: SHA-256 via crypto_hash_sha256

• Security: Audited, constant-time operations

JavaScript (Browser & Node.js)

• Primary: Web Crypto API (SubtleCrypto.digest)

• Fallback: libsodium-wrappers (WebAssembly)

• Security: Hardware-accelerated where available
